[Problem] from low nutrition food viscosity, nutritional foods, including high viscosity semi-solidified nutritional supplement, without being affected by the inherent viscosity to nutritional foods, nutritional food such as easily from the bag-like container, less likely to remain in the bag-like container, in a short time to provide a nutritional supplement injection assisting device for a pourable gastrostomy s stomach person via a gastric fistula. A set up a bag-like container 3 between the base plate 1 and one of the winding shaft 2, insert the bottom of the bag-like container 3 drilled groove opening to the take-up shaft 2, the take-up shaft 2 a bag-shaped container 3 placed on the line with base plate 1 to the electric drive rotation winding the winding shaft 2, by being wound on the winding shaft 2, reducing the volume of the bag-shaped container 3, and a bag-shaped container 3 internal pressure is generated in the, it is possible to inject from the stomach fistula in the patients stomach almost all nutritional foods in the interior of the bag-shaped container 3 through the tube 4. .BACKGROUND【課題】粘度の低い栄養食品から、粘度の高い半固形化栄養剤を含む栄養食品等を、栄養食品等に固有の粘度に影響されることなく、袋状容器から栄養食品等を容易に、袋状容器に残留することが少なく、短時間で胃瘻を経由して胃瘻患者に注入可能な胃瘻造設患者用栄養剤補給注入補助装置を提供する。【解決手段】袋状容器3を台板1と1個の巻取軸2の間に設置し、巻取軸2に開けられた溝開口に袋状容器3の底部を差し込み、巻取軸2の電気駆動回転にともない台板1の上に置かれた袋状容器3が巻取軸2に巻き付き、巻取軸2に巻き取られることにより、袋状容器3の体積が減り、袋状容器3の内部には内圧が発生し、袋状容器3の内部にある栄養食品等のほぼ全量がチューブ4を経由して胃瘻から患者の胃に注入することが可能となる。【選択図】図1
